THE INSTITUTE FOR ADVANCED STUDY PRINCETON, NEW JERSEY June 10, 1942 Dear Professor Mises, Here are the figures which you asked me to send you, with the exact reference in each case. You will please make no mention of my name in connection with any use of them. I was sorry the other day that I could not find Kerillis, but I hope to arrange a meeting with him the next time. Is shall write to you in advance. Yours most sincerely Think ranlous P.S. I have just seem the Statistisches Jahrbuch for 1931, where some of the figures of the Viertelsjahrheft fur Konj- unkturforschung are reproduced, giving different types of investment. You will see hat the totals are not the sane as those I noted. The latter refer only to "bereit- bestellten" Geldkapital. Other calculations of capital growth have also been computed, but I havenst the article at hand. (x) p.536.
